sheets, labels, etc. Failure to observe Safety Precautions can result in injury or death.

1 SAFETY

0463 691 001

- 5 -

PROTECT YOURSELF AND OTHERS

Some welding, cutting and gouging processes are noisy and require

hearing protection. The arc, like the sun, emits ultraviolet (UV) and

other radiation and can injure the skin and eyes. Hot metal can cause

burns. Training in the proper use of the processes and equipment is

essential to prevent accidents. Therefore:

1. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes

when welding or watching.

2. Always wear safety glasses with side shields in any work area, even if welding

helmets, face shields and goggles are also required.

3. Use a face shield fitted with the correct filter and cover plates to protect your eyes,

face, neck and ears from sparks and rays of the arc when operating or observing

operations. Warn bystanders not to look at the arc and not to expose themselves to

the rays of the electric-arc or hot metal.

4. Wear flameproof gauntlet-type gloves, heavy long-sleeve shirt, cuffless pants,

high-topped shoes, and a welding helmet or cap for protection, to protect against arc

rays and hot sparks or hot metal. A flameproof apron may also be desirable as

protection against radiated heat and sparks.

5. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves

and collars should be kept buttoned and open pockets eliminated from the front of the

clothing.

6. Protect other personnel from arc rays and hot sparks with a suitable non-flammable

partition or curtains.

7. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be

hot and can fly for long distances. Bystanders should also wear goggles over safety

glasses.

FIRES AND EXPLOSIONS

The heat from flames and arcs can start fires. Hot slag or sparks can

also cause fires and explosions. Therefore:

1. Protect yourself and others from flying sparks and hot metal.

2. Move all combustible materials well away from the work area or cover the materials

with a protective non-flammable covering. Combustible materials include wood, cloth,

sawdust, liquid and gas fuels, solvents, paints, and coating paper, etc.

3. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings

and cause a hidden smoldering fire or fires on the floor below. Make certain that such

openings are protected from hot sparks and metal.

4. Do not weld, cut, or perform other hot work until the work piece has been completely

cleaned so that there are no substances on the work piece which might produce

flammable or toxic vapors. Do not perform hot work on closed containers, they may

explode.

5. Have fire extinguishing equipment handy for instant use, such as a garden hose,

water pail, sand bucket, or portable fire extinguisher. Be sure you are trained in its

use.

6. Do not use equipment beyond its ratings. For example, an overloaded welding cable

can overheat and create a fire hazard.

7. After completing work, inspect the work area to make sure there are no hot sparks or

hot metal that could cause a fire later. Use fire watchers when necessary.

ELECTRICAL SHOCK

Contact between live electrical parts and earth can cause severe injury

or death. DO NOT use AC welding current in damp areas, if movement

is confined, or if there is danger of falling. Therefore:

1. Be sure the power source frame (chassis) is connected to the earth system of the

input power.

2. Connect the workpiece to a good electrical earth.

3. Connect the work cable to the workpiece. A poor or missing connection can expose

you or others to a fatal shock.

4. Use well-maintained equipment. Replace worn or damaged cables.

5. Keep everything dry, including clothing, work area, cables, torch/electrode holder and

power source.

6. Make sure that all parts of your body are insulated from both the work piece and from

the ground.

7. Do not stand directly on metal or the ground while working in tight quarters or a damp

area; stand on dry boards or an insulating platform and wear rubber-soled shoes.

8. Put on dry, hole-free gloves before turning on the power.

9. Turn off the power, before removing your gloves.

10. Refer to ANSI/ASC Standard Z49.1 for specific grounding recommendations. Do not

mistake the work lead for a earth cable.

ELECTRIC AND MAGNETIC FIELDS

May be dangerous. Electric current flowing through any conductor

causes localized Electric and Magnetic Fields (EMF). Welding and

cutting current creates EMF around welding cables and welding

machines. Therefore:

1. Welders with pacemakers fitted should consult their doctor before welding. EMF may

interfere with some pacemakers.

2. Exposure to EMF may have other health effects which are unknown.

3. Welders should use the following procedures to minimize exposure to EMF:

a) Route the electrode and work cables together. Secure them with tape when

possible.

b) Never coil the torch or work cable around your body.

c) Do not place your body between the torch and work cables. Route cables on

the same side of your body.

d) Connect the work cable to the workpiece as close as possible to the area being

welded.

e) Keep the welding power source and cables as far away from your body as

possible.

FUMES AND GASES

Fumes and gases, can cause discomfort or harm, particularly in

confined spaces. Shielding gases can cause asphyxiation. Therefore:

1. Keep your head out of the fumes. Do not breathe the fumes and gases.

2. Always provide adequate ventilation in the work area by natural or mechanical means.

Do not weld, cut or gouge on materials such as galvanized steel, stainless steel,

copper, zinc, lead beryllium or cadmium unless positive mechanical ventilation is

provided. Do not breathe in the fumes from these materials.

1 SAFETY

0463 691 001

- 7 -

3. Do not operate near degreasing and spraying operations. The heat or arc can react

with chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas, and other

irritant gases.

4. If you develop momentary eye, nose or throat irritation while operating, this is an

indication that the ventilation is not adequate. Stop work and take the necessary steps

to improve ventilation in the work area. Do not continue to operate if physical

discomfort persists.

5. Refer to ANSI/ASC Standard Z49.1 for specific ventilation recommendations.

6. WARNING: This product when used for welding or cutting, produces fumes or gases

that contain chemicals known to the State of California to cause birth defects and in

some cases cancer (California Health & Safety Code §25249.5 et seq.)

CYLINDER HANDLING

Cylinders, if mishandled, can rupture and violently release gas. A

sudden rupture of cylinder valve or relief device can injure or kill.

Therefore:

1. Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.

2. Use the proper gas for the process and use the proper pressure reducing regulator

designed to operate from the compressed gas cylinder. Do not use adapters. Maintain

hoses and fittings in good condition. Follow the manufacturer's operating instructions

for mounting a regulator to a compressed gas cylinder.

3. Always secure cylinders in an upright position, by chain or strap, to suitable hand

trucks, undercarriages, benches, wall, post or racks. Never secure cylinders to work

tables or fixtures where they may become part of an electrical circuit.

4. When not in use, keep cylinder valves closed. Have valve protection cap in place if

regulator is not connected. Secure and move cylinders by using suitable hand trucks.

MOVING PARTS

Moving parts, such as fans, rotors and belts can cause

injury. Therefore:

1. Keep all doors, panels, guards, and covers closed and securely in place.

2. Stop the engine or drive systems before installing or connecting a unit.

3. Have only qualified people remove covers for maintenance and troubleshooting as

necessary

4. To prevent accidental starting of equipment during service, disconnect negative (-)

battery cable from battery.

5. Keep hands, hair, loose clothing and tools away from moving parts.

6. Reinstall panels or covers and close doors when service is finished and before

starting engine.
